WILLIAM `CHADWICK AND SAMUEL LOWNDS,"OF BROOKLYN, NEW YOBK IMPROVEMENT IN coP-wiNDlNe MACHINES.

Specification forming part of Letters Patent No. 143`,497,dated October 7, 1873 application filed .Y Marcha-1,1873. f 1

To all 'whom t may concern.- Y

Be it known that we, WILLIAM CHAnwIcK and SAMUEL LOWNDS, both of Williamsburg, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cop-Winding Machines for Power-Looms, of which the following is a speciication:

In the cop winding or filling machine shown4 in the drawing, the invention consists in an automatic stop-rod, or device for disconnecting the winding-spindle, thereby insuring a uniform cop being built, and doing away with the loss of time and labor consequent on removing the copbefore it is fully built, or neglecting to remove it when fully built. The invention likewise includes or consists in an automatic catch contrivancev for holding the winding-spindle out of gear after it has been disconnected from the skewer or buildingspindle 5 furthermore, the invention includes an adjustable inger for lengthening or shortening the cop.- i

In the accompanying drawing, which forms part of this speciiication, vFigure l represents a font view of a cop winding or filling frame,

in part, having our improvements applied, Fig. 2, a side view of the same; Fig. 3, a front view, in part, showing the winding-spindle and its immediate devices in a different working position from that illustrated in Fig. l; and Fig. 4, a side view of the same. Fig. 5 is a vertical section, in part, in illustration of the winding-spindle5-and Fig. 6, a plan of a compound-lever arr( ngement for operating the building-rail.

Similar letters of reference indicate corresponding parts.

The cop winding or filling frame shown in the accompanying drawing may be extended indefinitely, to accommodate any number of Y means of a sleeve, YD, with which said spindle projections g 7L, to gear with the skewer or tapering building-spindle E, on which the cop Gr is wound, said building-spindle having its bearing below in the building-cup F. His the spool of yarn of which the cop is -to be built. Said yarn passes through or over and under tension-bars I I, and from thence through a guard, J,'on the building-rail K, and through a slot, i, in the building-cup. The building rail K has an up-and-down motion along guides lo 7c, said motion being derived from a shaft, L, driven by belt and pulleys l and l l', and being communicated to the building-rail by a wrist-pin, m, connected with the shaft L, a rod, n, and a system or combination of levers,M N, arranged to rock upon a common ful-cram, o, and connected with each other by a slot and screw, p, to provide for required change in the diameter of the cop. As the cop G is formed on the building-spindle E it rises in the cup F, and with it the winding-spindle B, until the cop has been built its required length, when a stop-rod, Q, connected with the winding-spindle B by a cord or chain, r, passing overa pulley, s, comes by its descent into lock or gear with the building-rail K by a hook or catch, t, on said rod engaging with or under a strap or projection, u, on the building-rail K during the upward movement of the latter, and so that as said rail descends it pulls the winding-spindle B up and out of gear with the building-spindle E, and thus automatically disconnects the winding-spindle. The period of thus disconnecting the winding-spindle B from the cop-spindle E is made adjustable, according to the length of cop required, by means of a linger, B, adjustable up or down in a holder, o, and arranged so that in the descent of the stop-rod Q, as the spindle B rises, it comes sooner or later in contact with a step, w, on the rod Q, and bears said rod to one side, so that it fails to engage by its hook t with the building-rail K until the step 'w is clear of the finger R, the position of which latter, therefore, determines the time of the building-rails disconnecting action on the stop-rod. Upon suchpdisconnection of the Winding-spindle B from the cop-building spindle E-that is, `as the former is drawn upWard by the action of the strap or projection u of the building-rail K on the hook t-a crank drop-catch, S, falls under and into lock with a rod, T, in rigid or permanent connection With the Winding-spindie B, so as to be Virtually a part of it. This automatically keeps or holds the Winding-spindle in its raised position, and out of gear with the building-spindle.

What is here claimed, and desired to be secured by Letters Patent, is-

l. The combination of the stop-rod Q, chain 1^, and pulley s with the Winding-spindle B, the building-rail K, and the building-spindle E, as shown and described, for the purpose specified.

2. The bell-crank catch S, in combination With the rod T, connected With the Windingspindle B, as shown and described, for the purpose specified.

.3. The finger R, capable of adjustment in `the holder v on the sleeve D, in combination with the step @con the stoprod Q, as shown and described, for the purpose specied.
